, 1 The present invention, relating as indicated to portable atomizers, has more particular regard to so-called pocket atomizers such as are largely used for spraying concentrated solutions of insecticide and cleaning compounds, perfumes and toilet liquids where a fine atomization is desired. .It will be understood, however, that the improved features which characterize the invention is not limited to atomizers of any particular size or for any particular field of use.

One principal object of the invention is to provide a readily portable pocket size atomizer which can be readily carried on the person of the user, which will be capable of producing the desired and necessary fine atomization of concentrated insecticidal solutions, and that will be ready for instant use without catches that require to be released or complicated valves that are apt to get out of order.

A further object of the invention is to provide an atomizer of the type in question in which the container for the liquid to be atomized is readily detachable and may be made of glass, as is desirable where the atomizer is used withcertain perfumes or other liquids which contain acids that act chemically on most metals. Such container at the same time serves as the actuating means for the device. A further object is to eliminate the use of a so-called syphon tube, the liquid to be atomized being led directly from one end of the container to the discharge nozzle. By providing a seal for the latter the device is accordingly made leakproof when in storage or while being carried about. The stream of air across such discharge nozzle will accordingly be all utilized to break up and atomize the liquid, none being required to raise or suck the liquid from the container.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

, In said annexed drawing:

a f a e erg n e. q aratlqae t e 2 device but on a somewhat larger scale in order better to show the detailed construction;

' Fig. 4 is a perspective view of the plunger, whereby the air is compressed, together with attached liquid container, shown as removed from the casing;

Figs. 5 and 6 are transverse sectional views of the device taken on the planes indicated by the lines 5- -5 and 6-6 respectively on Fig. 2; and

Fig. "7- is a sectional view on a larger scale of a recurved duct that leads from the inner end of the container to the discharge nozzle.

As clearly shown in Figs. 1 and 2, the main body of the atomizer consists of a cylindrical casing I that is closed at'its one end, such end being desirably reenforced with a cap 2 so as to constitute what may be regarded as the base of the device, although it maybe crried about, indifierently in any position, either vertical or horizontal. The opposite end of the casing is open, the-edge of the opening being bent slightly inwardly to form a flange 3 against which a second shorter shell or sleeve 4 that closely fits within casing l is adapted to abut. The inner end of said sleeve is formed with an inwardly directed flange 5 .(see Fig. 3) that is faced with a gasket 6 of rubber or like compressible material adapted toact as-a seal, the latter being'held in place by a second cylindrical flange I at the inner edge of-saidflange 5. Said flange I also serves toreceive and guide the piston, as will presently appear, and at the same time keeps possible expansion of the gasket from bindin and obstructing movement of said piston. The side wall of easing l is formed in its opposite sides with .two longitudinal openings 8 and?! which extend downwardly for some distance from points adjacent the lower edge of said gasket or sealing ring 6.

Reciprocally mountedin casing l between said sealing ring or gasket andthe closed end of the casing is a hollow piston l0, shown in section in Fig. 2 and'in perspective in Fig. 4. This piston carries the usual-washer l l at its lower "end so as to be adapted to compress air in'the-portion of the casing lyin between the piston and the lower end of the casing. A compression spring l2 interposed between the piston .and such lower casing end serves normally to move the forme away from the latter. The upper portion 13 of the piston is of reduced diameterso as to fit within the cylindrical flange l which by engagement with the offset on the piston acts as a stop, permitting the liquid discharge nozzleto press into the gasket to a predetermined depth 0nly.-. g .sucn portion. is

noted that the exterior diameter of the liquid container is smaller than the interior diameter of the casing including such sleeve, so that an air space is left therebetween, thus insulating the container to a substantial extent against transfer of heat, e. g. from the users hand when manipulating the device, or from other source. This is an important advantage where the liquid being sprayed contains a volatile ingredient.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed"- I therefore particularly point out and distinctly claim as my invention:

1. In an atomizer, the combination of a casing having a closed lower end, a piston reciprocable in said casing adapted to compress air in the portion thereof adjacent such end, said casing having a lateral Opening exposing a side por-v tion of said piston and the latter having a vent in such portion for discharge of compressed air,

Cir

a liquid container connected at its lower end to the upper end of said piston, a tube below said container having upwardly directed open ends respectively within and without said container, the ends of said tube being disposed below the level of the liquid in said container and providing the sole means of communication between the interior and exterior thereof, the end of said tube disposed without said container being adjacent to and transverse to such vent, said container serving as actuating means for said piston, a r, 1',

compression spring between said piston and casing, and a gasket in said casing above such lastnamed tube end, said spring yieldably urging said piston and container upwardly to elfect sealing engagement between such tube end and said gasket.

2. In an atomizer, the combination of a casing having a closed lower end, a piston reciprocable in said casing adapted to compress air in the portion thereof adjacent such end, said casing having a lateral opening exposing a side portion of said piston and the latter having a vent in such portion for discharge of compressed air, a liquid container connected at its lower end to the upper end of said piston, a tube below said 2,345,853

container having upwardly directed open ends respectively within and without said container, the ends of said tube being disposed below the level of the liquid in said container and providing the sole means of communication between the interior and exterior thereof, the end of said tube disposed without said container being adjacent to and transverse to such vent, said container serving as actuating means for said piston, a sleeve in said casing provided with a radially inwardly extending flange above such last-named tube end and a cylindrical flange projecting downwardly from the inner extremity of such flange, a deformable gasket in the recess so defined by said casing and such flanges, and means for forcing such last-named tube end into sealing engagement with said gasket.

3. In an atomizer, the combination of a casing having a closed lower end, a member reciprocable in said casing adapted to compress air in the portion thereof adjacent such end, said casing having a lateral opening exposing a side portion of said member and the latter having a vent in such portion for discharge of compressed air, a liquid container carried by said member, the latter being provided with a passage having its ends below the level of the liquid in said container and respectively opening within and without said container and providing the sole means of communication between the interior and exterior of the latter, the outer end of such passage being located transversely adjacent to such vent, a gasket in said casing above the outer end of such passage, and a compression spring interposed between said member and casing, said spring yieldably urging said member upwardly to effect sealing engagement between the outer end of such passage and said gasket.
